Cool, Clear, and Compact.

We’ve engineered the Carbide Clear 400C to pack all the performance and expandability you need into a beautifully compact case design. Put your components on display through the gorgeous, full-size window panel that opens with a touch — and keep it all running cool and quiet with Direct Airflow technology.

Easy to build, hard to beat

With a one-touch side panel, tool-free drive installation, and three-point dust filter access, 400C is easy to build and even easier to keep clean. You’ll spend less time on setup and maintenance, and more time enjoying your PC.

Hinged and latched full side panel window

Easily access your components with a single touch – and when it’s closed, enjoy viewing every part of your build through the full side panel window.

Clean, modern lines with an all steel exterior

Get rid of those plastic cases – the 400C has full steel front and top panels for extra durability and gorgeous good looks.

Direct Airflow Path

One way to reduce noise is to make sure your fans don’t work harder than they have to. By removing the drive cages behind the intake fans, we provide a more efficient direct airflow path to your hottest components, the CPU and GPU. It’s just a smarter design.

Compact design, full size capabilities

Don’t let the compact dimensions of the 400C fool you. It can house a full ATX motherboard and multiple GPUs.

Liquid cooling capable

With room for up to a 360mm radiator in front, a 240mm radiator on top, and a 120mm radiator in rear, you can choose to quiet down your GPU and CPU with liquid coolers just about wherever you want to.

Two included AF series fans

Great airflow doesn’t have to be noisy -- the AF120L and AF140L fans can push good amounts of air across your hottest devices without that annoying fan hum, and the direct airflow design of the 400C provides an excellent path for cold air to get to your hottest parts.

PSU and 3.5” Bay Cover

Clean up the inside of your case by tucking all those cables and less-attractive drives behind two modular, clean, and refined PSU and 3.5” bay covers. Or remove them for assembly – it’s up to you.

Easy to clean

Easily access dust filters on front, top, and bottom mean you’ll never spend more than a minute getting dust out of your system.
